Surface Flow Characteristics


Maryland's flow conditions are heavily influenced by its location along the Atlantic coast and the Chesapeake Bay, as well as its varied topography. The state experiences a humid subtropical climate, with hot and humid summers and mild winters. Major surface flows include the Potomac and Patuxent Rivers, which feed into the Chesapeake Bay. Reservoirs and dams such as the Conowingo Dam and Loch Raven Reservoir also contribute to the state's hydrology.
